From AOPA:

AVIATION LOSES TWO LEGENDARY FIGURES
William T. Piper Jr., former president and chairman of the board of Piper Aircraft, and Paul B. MacCready Jr., the inventor who developed the first human-powered aircraft, the Gossamer Condor, died at the end of August.

I heard about MacCready the other day. Hadn’t heard about Piper until just now.
